Product Description
The low-voltage distribution cabinet of general mine type PKD is a power distribution and control device specially designed for non-coal mines and other underground areas. It belongs to the general mine electrical equipment category (KY) and has a national mine equipment safety certificate (KA). Designed for use in chambers or control rooms where there is no risk of gas or coal dust explosions, as well as in conditions where there is no drip or dust penetration.
Main purpose
● Power distribution: Designed for use in three-phase alternating current power supply systems with a frequency of 50 Hz with a rated voltage of 1140 V, 660 V or 380 V for the reception and distribution of electricity.
● System Protection: Provides control, measurement and protection for isolated neutral power systems, including overload, short circuit and other protection.
Product Features
● Safety certification: It is mandatory to have “KA” (mine equipment safety mark) and “KY” (general mine equipment) certificates, which are the documentary basis for legal and safe use underground.
● High degree of protection: The protection degree is generally IP54, which effectively prevents the penetration of dust and splashing water, ensuring adaptation to the underground environment.
● Variety of materials: The housing can be made of stainless steel or cold rolled steel to meet different corrosion protection requirements.
● Wide range of models: The rated current covers a wide range, common models have a rated current from 63 A to 1000 A; Can be customized according to actual power needs.
Operating conditions
● Scope of application: Cameras or control rooms in underground areas of non-coal mines.
● Environmental conditions: Ambient temperature from –5°C to +40°C, relative humidity not more than 95%, no gases or vapors that destroy insulation.
